OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo de seguridad, constituido mediante Ia combinación funcional de dos elementos, uno destinado a situarse en Ia embocadura de acceso al depósito de combustible de los automóviles, y otro a su vez destinado a rematar Ia manguera de suministro de combustible de las estaciones de servicio, de manera que dotando a ambos elementos de medios de acoplamiento machihembrado específicos para los diferentes tipos de combustible, no exista Ia posibilidad práctica de que a un vehículo en concreto pueda suministrársele un combustible que no sea aquél para el que ha sido previsto, es decir que, por ejemplo, a un vehículo con motor de gasóleo no pueda suministrársele por error gasolina, y viceversa.The present invention relates to a safety device, constituted by means of the functional combination of two elements, one intended to be located at the mouth of access to the fuel tank of automobiles, and another in turn intended to finish off the supply hose of fuel at the service stations, so that by providing both elements with tongue and groove coupling means specific to the different types of fuel, there is no practical possibility that a particular vehicle can be supplied with a fuel other than that for which it has been foreseen, that is to say, for example, a vehicle with a diesel engine cannot be supplied by mistake, and vice versa.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, los vehículos automóviles incorporan un tubo de entrada a su depósito de combustible, cuya embocadura se sitúa a nivel de su carrocería, en posición de fácil accesibilidad para introducir en el seno de Ia misma Ia boquilla que remata las mangueras de los surtidores de combustible, siendo estos elementos esencialmente cilindricos y de dimensiones prácticamente constantes en el caso de las boquillas y que presentan ligeras diferencias de un fabricante a otro en el caso de los tubos de entrada a los depósitos de combustible de los vehículos, de manera que cualquier boquilla puede ser introducida en el tubo de cualquier depósito, además con una notable holgura.
La utilización de estos elementos se hace extensiva y común tanto a vehículos con motor de gasóleo como a vehículos que funcionan con diferentes tipos de gasolina.As is known, motor vehicles incorporate an inlet tube to their fuel tank, whose mouthpiece is located at the level of their bodywork, in an easily accessible position to introduce the nozzle that finishes the fuel hoses hoses of fuel, these elements being essentially cylindrical and of practically constant dimensions in the case of the nozzles and that present slight differences from one manufacturer to another in the case of the inlet tubes to the fuel tanks of the vehicles, so that any Nozzle can be introduced into the tube of any reservoir, in addition to a noticeable slack. The use of these elements is extensive and common both to vehicles with diesel engines and to vehicles that run on different types of gasoline.
Ello supone un permanente riesgo de que se produzcan equívocos, de manera que a un determinado vehículo automóvil se Ie suministre un combustible distinto de aquél para el que está previsto, Io que en Ia práctica da lugar a importantes averías de costosa reparación.This implies a permanent risk of misunderstandings, so that a specific motor vehicle is supplied with a fuel other than that for which it is intended, which in practice leads to significant costly repair breakdowns.
Este problema se agrava cuando, como cada vez está más generalizado, las estaciones de servicio funcionan en régimen de autoservicio, y es el propio conductor de cada vehículo el que debe efectuar Ia maniobra en cuestión, de manera que su inexperiencia incrementa considerablemente el riesgo de error.This problem is exacerbated when, as it is increasingly widespread, the service stations operate under self-service, and it is the driver of each vehicle who must perform the maneuver in question, so that its inexperience greatly increases the risk of error.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El dispositivo de seguridad que Ia invención propone resuelve de forma plenamente satisfactoria Ia problemática anteriormente expuesta.The security device proposed by the invention solves in a fully satisfactory manner the problem set forth above.
Para ello y de forma más concreta dicho dispositivo consiste, como anteriormente se ha dicho, en Ia combinación funcional de dos elementos, uno acoplable a Ia embocadura del tubo de entrada del depósito de combustible, y otro acoplable a su vez a Ia extremidad libre de Ia boquilla que remata Ia manguera de los surtidores, con Ia especial particularidad de que dichos elementos determinan un acoplamiento machihembrado diferente para cada tipo de combustible, como por ejemplo triangular para Ia gasolina convencional, cuadrangular para Ia gasolina sin plomo y hexagonal para el gasóleo, sin que estas configuraciones sean en modo alguno limitativas, de manera que a un vehículo previsto para utilizar un determinado tipo de combustible, no exista
posibilidad práctica de suministrarle un combustible distinto, por cuanto que tan sólo Ia boquilla correspondiente es susceptible de penetrar en el tubo de depósito.For this, and more specifically, said device consists, as previously stated, in the functional combination of two elements, one that can be connected to the mouth of the fuel tank inlet tube, and another that can be connected to the free end of The nozzle that ends the hose of the jets, with the special feature that said elements determine a different tongue and groove coupling for each type of fuel, such as triangular for conventional gasoline, quadrangular for unleaded gasoline and hexagonal for diesel, without these configurations being in any way limiting, so that a vehicle intended to use a certain type of fuel does not exist practical possibility of supplying a different fuel, since only the corresponding nozzle is capable of penetrating the reservoir tube.
De acuerdo con otra de las características de Ia invención se ha previsto que las dimensiones exteriores del elemento destinado a fijarse a Ia boquilla de Ia manguera del surtidor sean tales que permitan su acoplamiento en el tubo de entrada al depósito de combustible de cualquier vehículo carente del elemento complementario, al objeto de que todos aquellos vehículos desprovistos del dispositivo de seguridad que Ia invención propone puedan repostar en cualquier gasolinera o estación de servicio.In accordance with another of the characteristics of the invention, it has been provided that the external dimensions of the element intended to be fixed to the nozzle of the hose of the dispenser are such that they allow its coupling in the inlet pipe to the fuel tank of any vehicle lacking the complementary element, in order that all those vehicles devoid of the safety device proposed by the invention can refuel at any gas station or service station.
De acuerdo con otra de las características de Ia invención se ha previsto también que el elemento destinado a acoplarse a Ia entrada del depósito de combustible esté fraccionado diametralmente en dos mitades, relacionadas entre sí mediante muelles y pasadores, de manera que resultando dicho elemento adaptable, con sus dos mitades íntimamente unidas, aquellos vehículos con un tubo de entrada de diámetro mínimo, sean igualmente acoplables a tubos de entrada de otros diámetros, mediante expansión elástica y automática del elemento.In accordance with another of the characteristics of the invention, it is also provided that the element intended to be coupled to the fuel tank inlet is diametrically divided into two halves, interconnected by means of springs and pins, so that said adaptable element results, with its two intimately joined halves, those vehicles with an inlet tube of minimum diameter, are equally attachable to inlet tubes of other diameters, by elastic and automatic expansion of the element.
Evidentemente, y tras una implantación generalizada del dispositivo de seguridad en el mercado, los dos elementos componentes del dispositivo pueden constituir, en lugar de piezas independientes acoplables respectivamente al tubo de entrada del depósito y a Ia boquilla del surtidor, elementos integrados de fábrica en los mismos que rematen, con carácter monopieza, tanto el tubo de entrada al depósito combustible como Ia complementaria boquilla.Obviously, and after a generalized implementation of the safety device on the market, the two component elements of the device may constitute, instead of independent parts, respectively coupled to the inlet tube of the tank and to the nozzle of the dispenser, factory integrated elements therein that finish, with a single piece character, both the inlet pipe to the fuel tank and the complementary nozzle.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
En las figuras reseñadas se ha referenciado con (1) Ia boquilla que remata Ia manguera de un surtidor de los utilizados en gasolineras o estaciones de servicio, y con (2) el tubo de entrada al depósito de combustible de cualquier vehículo, integrado en Ia carrocería (3) del mismo, concretamente emergiendo
del fondo del clásico alojamiento (4) obturable mediante una tapa practicable (5).In the figures described, reference has been made to (1) the nozzle that ends the hose of a dispenser used in gas stations or service stations, and with (2) the inlet pipe to the fuel tank of any vehicle, integrated in Ia body (3) thereof, specifically emerging from the bottom of the classic housing (4) sealed by a practicable cover (5).
Pues bien, de acuerdo con Ia invención en el dispositivo participa un primer elemento (6) dotado de un cuello cilindrico (7), interiormente roscado para su acoplamiento a Ia extremidad libre (8) de Ia boquilla (1), en Ia que mediante una terraja o similar se efectuará un roscado complementario, adoptando el citado elemento (6), en su sector ajeno al citado cuello (7), una configuración exteriormente poligonal, como por ejemplo Ia configuración triangular mostrada en Ia figura 1 o cualquiera de las configuraciones que muestra Ia figura 5, entre otras muchas que son igualmente válidas, como se verá más adelante.Well, according to the invention in the device a first element (6) is provided with a cylindrical neck (7), internally threaded for coupling to the free end (8) of the nozzle (1), in which by a tap or similar will be a complementary thread, adopting said element (6), in its sector outside the said neck (7), an externally polygonal configuration, such as for example the triangular configuration shown in Figure 1 or any of the configurations which shows Figure 5, among many others that are equally valid, as will be seen later.
El elemento (6) se complementa con un segundo elemento (9) destinado a acoplarse a Ia embocadura del tubo de entrada (2) al depósito de combustible del vehículo, elemento (9) que adoptará una configuración extema sensiblemente cilindrica, para su correcta adaptación a dicho tubo (2), pero cuyo interior hueco (10) será también de configuración poligonal, acorde con Ia del elemento (6) complementario.The element (6) is complemented by a second element (9) intended to be coupled to the inlet of the inlet pipe (2) to the fuel tank of the vehicle, element (9) that will adopt a substantially cylindrical external configuration, for its correct adaptation to said tube (2), but whose hollow interior (10) will also be of polygonal configuration, in accordance with that of the complementary element (6).
De esta manera y dotando por ejemplo a los vehículos que funcionen con gasolina clásica de elementos (6) y (9) con Ia configuración triangular mostrada en las figuras 1 y 2, y dotando a las boquillas (1) de los surtidores de este tipo de combustible, de una configuración también triangular, y utilizando por ejemplo una configuración cuadrangular para tales elementos en el caso de gasolina sin plomo, y una configuración hexagonal para vehículos y surtidores de gasóleo, desaparece Ia clásica posibilidad de error en el suministro de combustible, ya que en cada vehículo concreto sólo podrá ser acoplada Ia boquilla del combustible que Ie corresponde.In this way and providing, for example, the vehicles that run on classic gasoline with elements (6) and (9) with the triangular configuration shown in figures 1 and 2, and providing the nozzles (1) with the suppliers of this type of fuel, of a triangular configuration, and using for example a quadrangular configuration for such elements in the case of unleaded gasoline, and a hexagonal configuration for vehicles and diesel pumps, the classic possibility of error in the fuel supply disappears, since in each specific vehicle only the corresponding fuel nozzle can be attached.
Dado que, como anteriormente se ha dicho, existen ligeras diferencias dimensionales en el tubo de entrada (2) al depósito de combustible
de diferentes tipos de vehículos, se ha previsto que el elemento (9) destinado a acoplarse en los mismos esté fragmentado diametralmente en dos mitades (9- 91) relacionadas entre sí mediante pasadores (11) y muelles (12) que tienden a Ia separación elástica de dichas dos mitades, de manera que dicho elemento (9) puede adoptar Ia disposición de dimensiones mínimas mostrada en Ia figura 2, cuando se monte sobre un vehículo cuyo tubo de entrada (2) sea también de dimensiones mínimas, adecuándose automática y elásticamente a tubos de mayor diámetro, a los que quedará igualmente fijado por simple acoplamiento axial.Since, as previously stated, there are slight dimensional differences in the inlet pipe (2) to the fuel tank of different types of vehicles, it is provided that the element (9) intended to be coupled thereto is diametrically fragmented into two halves (9-9 1 ) interconnected by means of pins (11) and springs (12) that tend to elastic separation of said two halves, so that said element (9) can adopt the arrangement of minimum dimensions shown in Figure 2, when mounted on a vehicle whose inlet tube (2) is also of minimum dimensions, automatically adapting and elastically to larger diameter tubes, which will also be fixed by simple axial coupling.
Sólo resta señalar por último que, como también se ha dicho con anterioridad, las dimensiones exteriores máximas del elemento (6) acoplable a Ia boquilla (1) del surtidor, deben ser tales que permitan su introducción en el tubo de entrada (2) de cualquier vehículo desprovisto del elemento complementario (9), para no limitar Ia utilización práctica del surtidor en cuestión y que, como realización práctica a medio o largo plazo, el elemento (6) en lugar de ser acoplable a ia boquilla (1) puede estar integrado de fábrica en dicha boquilla (1), de Ia misma manera que el elemento (9) puede estar integrado con carácter monopieza en el tubo de entrada (2) al depósito de combustible de los automóviles.
It only remains to indicate finally that, as it has been said previously, the maximum external dimensions of the element (6) attachable to the nozzle (1) of the spout, must be such that they allow its introduction into the inlet tube (2) of any vehicle devoid of the complementary element (9), so as not to limit the practical use of the supplier in question and that, as a practical medium or long-term realization, the element (6) instead of being attachable to the nozzle (1) may be Factory integrated in said nozzle (1), in the same way that the element (9) can be integrated as a single piece in the inlet pipe (2) to the fuel tank of cars.
